There is no exception to the major questions doctrine for emergency
statutes. Nor does the fact that tariffs implicate foreign affairs render
the doctrine inapplicable. The Framers gave “Congress alone” the
power to impose tariffs during peacetime. Merritt v. Welsh, 104 U. S.
694, 700. And the foreign affairs implications of tariffs do not make it
any more likely that Congress would relinquish its tariff power
through vague language, or without careful limits.

(a) IEEPA authorizes the President to “investigate, block during the
pendency of an investigation, regulate, direct and compel, nullify, void,
prevent or prohibit . . . importation or exportation.” §1702(a)(1)(B).
Absent from this lengthy list of specific powers is any mention of tariffs
or duties. Had Congress intended to convey the distinct and extraordinary power to impose tariffs, it would have done so expressly, as it
consistently has in other tariff statutes.
The power to “regulate . . . importation” does not fill that void. The
term “regulate,” as ordinarily used, means to “fix, establish, or control;
to adjust by rule, method, or established mode; to direct by rule or restriction; to subject to governing principles or laws.” Black’s Law Dictionary 1156. The facial breadth of this definition places in stark relief
what ”regulate” is not usually thought to include: taxation. Many statutes grant the Executive the power to “regulate.” Yet the Government
cannot identify any statute in which the power to regulate includes the
power to tax. The Court is therefore skeptical that in IEEPA—and
IEEPA alone—Congress hid a delegation of its birth-right power to tax
within the quotidian power to “regulate.”
While taxes may accomplish regulatory ends, it does not follow that
the power to regulate includes the power to tax as a means of regulation. Indeed, when Congress addresses both the power to regulate and
the power to tax, it does so separately and expressly. That it did not
do so here is strong evidence that “regulate” in IEEPA does not include
taxation.

Supreme Court absolutely bodies Trump on IEEPA.

Just complete groin kicking.

They could have said that IEEPA lets him impose tariffs in an emergency but that this didn't qualify as one of those, or he failed to define one.

It didn't.

It ruled IEEPA doesn't let him impose tariffs at all.

Donald Trump shocked Europe when he threatened the continent with tariffs to support his right to own Greenland.

But while the U.S. President has aborted his threat to take the Arctic island by force — online, the war is just getting started.

Push by lawmakers to ban Russian steel sets up clash with EU capitals The EU imported more steel from Russia in 2025. The European Parliament now sees a unique chance to ban it.

The EU already had its work cut out to agree to impose a 50 percent tariff on steel imports by a summer deadline. Now, an attempt by lawmakers to graft a ban on Russian steel onto the measure has made things a lot more complicated.

Trump Is No Game Theorist Koichi Hamada highlights a fundamental flaw in the US president’s tariff policy, particularly with regard to China.

When the US raises tariffs on close allies, such as Japan and the EU, it can leverage the security guarantees on which they depend to discourage them from retaliating, notes Koichi Hamada. The same is not true for China. bit.ly/4ajn3PF
